Slightly OT but, does anyone know what this look is called? I have seen pics like that and I just love it. I am a beginner in PS, so I think it has to be achieved by color grading but how? It's good something of, I don't know how to describe it, woody color or you know slight black and white while the leaves really pop.I would be grateful if someone can point me to some tutorial.

No problem -o well you'd use a graident and then set to color or overlay or even soft light or screen if you want it softer.... depending on the look you want.... or you can go to the layer's properties and go to the graident section and do it from there as well...
